JAMES MOONEY, OF CLARION, FENNSYLVANIA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 422,031, dated February25, 1890.

' Application filed November 14, 1889. Serial No. $30,304:. (N0 model.)

To aZZ whom it may concern:

Be it known that I, JAMES MOONEY, a citizen of the United States,residing at Clarion, in the county of Olarion and State of Pennsylvania,have invented certain new and use ful Improvements in Oar-Couplings;andI do hereby declare the following to be a full, clear, and eXactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. a

My invention relates to car-couplings, and has for its object certainimprovements in construction, which will be hereinafter described, andparticularly pointed out in the claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a plan of my improved coupling; Fig. 2, alongitudinal section; Fig. 3, a horizontal section; Fig. 4., aperspective of the trippingblock, and Fig. 5 a front elevation.

Reference being had to the drawings and the letters thereon, A indicatesa frame of timber, secured under a car in the usual manner; B, adraw-bar suspended in said frame upon a yoke or stirrup O at the frontend of the draw-bar and upon a transverse pin or rod D, which passesthrough the drawbar and side supports E F. The side supports areprovided with grooves a and laterally and inwardly projecting lugs I),upon which the draw-bar rests, and the draw-bar and said side supportsare embraced by the yoke or stirrup 0. To the free ends of the yoke isapplied a bar G, secured thereto by nuts 0, and in said bar is pivotallysecured a rod H at (Z to allow the draw-bar to swing or vibratelaterally in rounding curves in a road-bed, and the upper end of said.rod is screw-threaded, as at e, and provided with a rocation of thedraw-bar in the frame A when the draw-bar is struck by another one incoupling, or when a train of cars is started, as will hereinafter morefully appear.

Within the draw-bar is a chamber 2', the bottom of which is below theplane of the link-opening 7c in the head Z of the draw-bar, and withinthis chamber are contained the end of the link I, a tripping-block K,blocks or abutments m, n, and o, and springs p q. To the tripping-blockK is attached an arm T, which is secured thereto by a screw-threaded rod5, which works in a slot t in the lower side of the draw-bar for movingthe block into position under the coupling-pin L to be tripped byanapproaching car, with whose coupling the link I engages. The position ofthe tripping-block when under the couplingpin is shown in dotted linesin Fig. 2.

At the inner end of the frame A is placed a buffer consisting of a looseplate a, supported upon bolts o, and a piece or pieces of rubber w,secured to the end cross-piece 0c of the frame.

The first impact or jar of approaching cars in coupling is taken up bythe spring 1); but should the cars come together with great force thedraw-bar is driven back and cushioned upon the buffer in the frame A. Instarting the train the first movement of the car is taken up by thespring q until all of the links are in contact with their coupling-pinsat both ends, when the strain is transferred to the pins.

The link I is provided with a slot a at one end for engagement with onepin, an aper ture h for engagement with another pin, and a weightedextension 0' beyond said aperture for the purpose of overbalancing theslotted portion of the link and causing it to elevate said slottedportion to cause the link to enter the link-opening k in an approachingdraw bar. The application of the link to the drawbar is shown in Fig. 2.The near end of the chamber 2' is closed by aplate cl, of which theblock 0 forms an integral part and is secured in the draw-bar by boltse, passing through the draw-bar and the block, and the block m issecured in the chamber 6 by bolts f Having thus fully described myinvention, what I claim is- 1. In a car-coupling, a draw-bar,avertically-adj ustable yoke in which the draw-bar is supported at itsfront end, and a pin passing transversely through and supporting thedraw-bar at its rear end,in combination with a link and apin,substantially as described.

2. In a car-coupling, a draw-bar, a vertically-adj ustable andlaterally-vibrating yoke in which the draw-barissupported at its frontend, slots in the sides of the draw-bar near its rear end, and a pinpassing through said slots, in combination with a link and a pin,substantially as described.

3. In a car-coupling, a draw-bar, verticallymovable supports on thesides of the drawbar, a' yoke embracing said supports and the draw-barat the front end, a bar connecting the free ends of the yoke, means foradjusting the draw-bar vertically, and a pin at the rear end passingtransversely through the draw-bar, in combination with a link and a pin,substantially as described.

4:. In a car-coupling, a draw-bar, verticallyadjustable supports on thesides thereof, a yoke embracing said supports and the draw-bar at thefront end, a bar attached to the upper end of the yoke, a rod pivotallyconnected to said bar, an adjusting-Wheel at the opposite end of saidrod, and a support for the Wheel, in combination with a link and a pin,substantially as described.

5. In a car-coupling, a draw-bar having a link-chamber in the headthereof, the bottom of which is below the plane of the link-opening inthe head, in combination with a tripping-block having an extensionprojecting through the d raw-bar, a link having a slot for onecoupling-pin, an aperture for another pin, and aweighted extensionbeyond said aperture, and suitable pins for engaging said slot andaperture, substantially as described.

6. In a car-coupling, a reciprocating drawbar, a support at the frontend thereof, slots in the sides and near the rear end of the bar, achamber within the bar, blocks or abutments in said chamber, and springsbetween said blocks, in combination with a frame and a pin engaging withthe frame and passing through the draw-bar and the middle block,substantially as described.

'7. In a car-coupling, a drawbar, a yoke in which the draw-bar issuspended, a transverse pin, and slots in the draw-bar, in combination.with a frame fiXed to the car and a buffer at the inner end of saidframe, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
